The 2026 TM 250 Two-Stroke U.S. Race Edition is unlike anything else in motocross. Built in Italy and imported through 71 Powersports, the U.S. Race Edition takes TM’s already unique 250 two-stroke and adds a collection of race-focused upgrades, including a VHM cylinder head, DPR pipe and silencer, GBrakes’ steel-braided front brake line, holeshot device and custom race-team graphics package. The best part? It’s still eligible for stock-class racing at the amateur level.
In this MXA video test, we put the 2026 TM 250 U.S. Race Edition through weeks of riding, racing and tuning. We break down the smooth, torque-focused powerband, discuss the electronic power-valve system, explain the simple modification that transformed second-gear performance, and share the jetting changes that helped eliminate detonation and unlock the bike’s full potential.
